Can't ping 127.0.01 (Local Host)

[Ghazaroosian Vatche Neshan]

Hi

I am running a simple network with 3 Win2K pro computers connected to each
other via a hub & router computers A & B can see & communicate with each
other & get connected to the internet the third one, C, doesn't see A & B
but has Internet connection I tried to ping the local host 127.0.0.1 and got
100% loss, I changed the NIC card and the patch cord with the same result,
With Computer C I can ping any IP Address successfully?
would anybody have an where the error is?

Thanks

Under normal circumstances not being able to 127.0.0.1 is a hardware failure
of the NIC. In this case, since the NIC has been replaced, I would be
inclined to ask if you have any firewall software installed on this
computer?

I hope this helps...

Ron

Hello Ron

You are right the firewall software on Computer C was not configured
correctly, now it works, i can ping 127.0.0.1
